We are working on TAN application as per ASTM D664 method.
Autosampler: InMotion Flex 100ml
Customer samples are used and fresh lube oils.
The problem is this, results are in range but consumption of KOH is very high and the potential is not reached earlier. We have set the end point criteria at potential because in this application EQP is same time detect or some time no EQP.
This too much consumption of KOH is due to electrode worn out? Or some other issue.
How do we set this application to use less KOH.
Customer does 30 samples on daily basis.
Thanks and Best Regards,
